Description
Conclusions and Future Work
More modules and more functionalities are being implemented, as well as an optimization of existing ones, initially integrated off-the-shelf, e.g. by using struts as a development framework for java web application. As an example of a tool which we are implementing, we are actively working on a tool for automatic emergency shutdown and restart, and for programmed shutdown and restart for maintenance downtimes, on a rack basis.
Impact
The system we realized represents an integrated system, giving to most users a unique approach in accessing the grid Data Center; in particular, for the management team, it allows a thorough integration of all monitoring subsystems, and thus able to easily accommodate new hardware and software tools, thus following the evolution of the Data Center. For first-level monitoring, the approach we followed guarantees a simplified view of the infrastructure, so that operators shifts do not need very qualified personnel. We realized our own modules for a lot of equipment, but we also integrated existing applications such as GRIDICE – GANGLIA – POWER FARM. Such an integration strategy is in our opinion very useful in a situation, like the one in EGEE, in which a single tool is not enough for an exhaustive management of all the aspects of the Data Center.
Detailed analysis
We are approaching the integration of applications for monitoring, realizing a portal-integration (PI) and an enterprise-information-integration (EII).
The work we have done has followed this path: (i) identification of the functionalities that need to be monitored, along with their characteristics; (ii) identification of the already available commercial or self-made software products, if any; (iii) identification of the available open–source software; and (iv) development of dedicated plug -in and java web – applications.
The work has been carried out because of the need of having a dedicated troubleshooting and monitoring system for the newly built Data Center (we opened on february 2009), for which we needed a robust, flexible and easily adaptable system, without the complexity of functionalities often present in commercial systems but of rare usage, if any. But soon the job moved to the construction of a true portal system for the Data Center, which shall soon become the unique point-of-entry for all kinds of access, from the novice user, the expert user, the management team, and the referee group which has its role in future funding.
